Tourmaline Gemstone :
Tourmalines come in a wide variety of exciting colors. In fact, tourmaline has one of the widest color ranges of any gem species, occurring in various shades of virtually every hue. Tourmaline is the most colorful of all gemstones. It occurs in all colors, but pink, red, green, blue and multicolored are its most well-known gem colors. Scientifically, tourmaline is not a single mineral, but a group of minerals related in their physical and chemical properties. The mineral Elbaite is the member of the Tourmaline group that is responsible for almost all the gem varieties. Three other members of the group - Schorl, Dravite and Liddicoatite, are seldom used as gemstones. Purists say the only true Paraiba tourmaline is that which comes from Paraiba, Brazil, but it can also be found in Mozambique. “Brazilian stones are generally more expensive and have stronger color saturation, however they tend to be smaller, more included and harder to come by,” says Hubert Gesser of Hubert Gem, Los Angeles. “Mozambique stones tend to be cleaner, larger and lighter in saturation. Both can be beautiful.” Gesser acknowledges “there is disagreement within the trade on whether the non-Brazilian gems should be called Paraiba. Some believe only the stones from the state of Paraiba in Brazil can carry that name, while others believe that the term ‘Paraiba’ implies a specific color of primarily neon greenish blue, to stronger blues. Some labs describe the stones from Africa as: “copper bearing elbaite tourmalines, commonly referred to as ‘Paraiba’ within the trade, although the stones may not be from that location,” says Gesser.

NeutreI really don't understand this seller. He only shipped when threatened by the GRA managers I turned to. However, the stone arrived and is beautiful, albeit with some cracks not visible in the announcement. Be careful if you buy from them and be strict.

Pourquoi les utilisateurs se surenchérissent-ils ?
Lorsqu'une enchère est placée, il s'agit du montant maximum qu'une personne est prête à enchérir pour le produit. Notre système enchérira alors automatiquement au nom de l'enchérisseur, augmentant progressivement l'enchère jusqu'au maximum pour maintenir sa position de meilleur enchérisseur.
Lorsqu'une icône indiquant « Enchère automatique » apparaît, cela signifie que notre système place activement des enchères pour l'enchérisseur en fonction de son enchère maximale. Cela peut donner l'impression que les enchérisseurs se surenchérissent, mais c'est simplement le résultat de la mise à jour de l'enchère par le système pour refléter la limite maximale des enchérisseurs.
